An Overview of EIGRP Over the Top (OTP)

234 Words. Plan about 1 minute(s) to read this.

I wrote up a summary of Cisco’s newly announced EIGRP OTP feature for my blog on Network Computing. OTP is pretty interesting.

“EIGRP Over the Top (OTP) allows EIGRP routers to peer across a service provider infrastructure without the SP’s involvement. In fact with OTP, the provider won’t see customer routes at all. EIGRP OTP acts as a provider-independent overlay that transports customer data between the customer’s routers.

To the customer, the EIGRP domain is contiguous. A customer’s EIGRP router sits at the edge of the provider cloud, and peers with another EIGRP router a different location across the cloud. Learned routes feature a next hop of the customer router — not the provider. Good news for service providers is that customers can deploy EIGRP OTP without their involvement.”

For those who care, I go as deeply into OTP as I can in the post, which you can just click through to and read with no registration, AFAIK. There’s a limited amount of information that I could find, but there’s a reasonably complete picture painted. Certainly good enough to get the idea of what’s going on. I’m hoping Cisco’s Donnie Savage will have the cycles (and permission of his handlers) to record a Packet Pushers podcast on OTP, like he did to discuss Open EIGRP in show 144 along with Russ White.
